I have four chickens, they are all 22-24 weeks, and no eggs yet! I'm worried that because the days will be getting shorter I will not see any eggs until next summer! The weather has been gorgeous, we had a pretty mild summer, they've been on layer food for a month now, they have a 8 x 10 coop with an attached 8 x 8 run and get nothing but fresh air - any ideas what is going on? I have a barred rock, an americauna, a rhode island red, and a golden laced wyandotte. Any help on what they might need will be appreciated!
